Optical fiber communications
The third edition of this popular text and reference book presents the fundamental principles for understanding and applying optical fiber technology to sophisticated modern telecommunication systems.
Optical-fiber-based telecommunication networks have become a major information-transmission-system, with high capacity links encircling the globe in both terrestrial and undersea installations. Numerous passive and active optical devices within these links perform complex transmission and networking functions in the optical domain, such as signal amplification, restoration, routing, and switching. Along with the need to understand the functions of these devices comes the necessity to measure both component and network performance, and to model and stimulate the complex behavior of reliable high-capacity networks.

Substituting Eqs. (6-21) and (6-25) into Eq. (6-20), we have that the total current
density through the reverse-biased depletion layer is The term involving pM is
normally small, so that the total photogenerated current is proportional to the
For fully depleted photodiodes the rise time rr and fall time x/ are generally the
same. However, they can be different at low ... In this case, charge carries
produced in the depletion region are separated and collected quickly. On the
other hand, ...
